I have a 6.5 h. p. , 169cc,ohc/ohv, Robin/Subaru engine, mounted on a Scorpion dune buggy.When moving it?
releases a cloud of white/blue exhaust about every half mile.The choke is fully opened. I replaced the spark plug. Are there any opinions on how to correct the problem?
sounds like there is oil getting past the valve guide seals.
